Features & benefits

Superior RF performance

RF performance that meets exacting demands

The R&S®FSW redefines the top of the line for signal and spectrum analyzers, offering superior RF performance in terms of phase noise, displayed average noise level, intermodulation suppression and dynamic range for ACLR and harmonic measurements.

Be ahead in 5G development

The R&S®FSW scalable, wide internal analysis bandwidth of up to 2 GHz allows you to capture the entire bandwidth of the downlink signal and evaluate the complete system.

The R&S®FSW-K144 and R&S®FSW-K145 options cover in-band measurements of 3GPP 5G NR in the downlink and uplink. Each signal subframe is analyzed and a wide range of measurement results are provided, including the EVM, frequency and power of different channels and signals.

Ideal for satellite RF testing

The R&S®FSW offers dedicated measurement applications for the most critical measurements such as group delay, linearity, gain transfer, noise power ratio (NPR), etc. It also demodulates satellite RF signals of several standards such as DVB-S2X and OneWeb. The R&S®FSW scalable, wide analysis bandwidth (up to 2 GHz internally, 5 GHz with the R&S®RTO oscilloscope)meets the increasing demand for wide signal bandwidths.

Real-time spectrum analysis

Don’t miss a thing with the real-time spectrum analysis option

The R&S®FSW real-time options allow users to reliably detect extremely short sporadic interference in the nanosecond range even in close proximity to powerful carriers – in a bandwidth of up to 800 MHz. Real-time spectrum analysis enables users to analyze existing frequency hopping algorithms and create alternative ones to prevent collisions between signals of different standards operating in the same frequency band.

Digital signal analysis

The R&S®FSW-K70 vector signal analysis option enables users to flexibly analyze digitally modulated single carriers down to the bit level. The clearly structured operating concept simplifies measurements despite a wide range of analysis tools.The R&S®FSW-K70M allows analysis of signals with two different modulation schemes, such as DVB-S2X signals.The R&S®FSW-K70P extension measures the raw bit error rate (BER) on PRBS data up to PRBS23.

Be first in 5G signal generation and analysis - presented at GSMA MWC 2017

Rohde & Schwarz demonstrated 5G component characterization at 28 GHz at the GSMA Mobile World Congress 2017 in Barcelona. The R&S®SMW200A vector signal generator supports signal generation in line with the 28 GHz pre-5G specification available at www.5gtf.org. Combined with the R&S®FSW signal and spectrum analyzer supporting an internal 1.2 GHz analysis bandwidth, it is the ideal setup for in-depth component characterization such as for 28 GHz power amplifier development.
